摘    要:以土地利用变更调查数据和2013年我国各类土地生态系统单位生态服务价值为基础,估算2005、2009和2013年安徽全省及各地市生态系统服务价值,分析安徽省生态系统服务价值总量、构成与质量的时空分布。研究发现,2005、2009和2013年安徽省生态系统服务价值分别为3846.055、3788.165和3754.096亿元。研究期间,各项生态服务功能价值、各类用地对区域内生态服务系统价值贡献大小的排序均未改变。湿地、水域、耕地和草地4类用地的减少,是区域生态系统服务价值下降主因。六安、安庆、宣城、黄山、滁州、合肥和池州7市生态系统的稳定,对于维系全省生态环境质量有举足轻重的作用。2013年各地市生态系统服务质量呈现明显的地带性分布规律,自南向北逐渐递减。

关 键 词:安徽  土地利用/覆被变化  生态系统服务价值  生态系统服务质量

Abstract:According to the survey data on land use changes obtained from the Department of Land and Resources of Anhui Province and the national ecosystem service values of various types of land units in 2013, we estimated the ecosystem service values of Anhui in 2005, 2009, and 2013 and analyzed its structure and spatiotemporal features. We found that the ecosystem service values of Anhui in 2005, 2009, and 2013 were 384.6055, 378.8165, and 375.4096 billion yuan, respectively. During the study period, the rank of each ecosystem service function value and the rank of contribution of individual land use types to the regional ecosystem service values were not changed. The main reason for the decline of regional ecosystem service value was the reduction of wetland area, water area, cultivated land, and grassland. The ecosystem stability of Lu''an, Anqing, Xuancheng, Huangshan, Chuzhou, Hefei, and Chizhou has been playing a decisive role in maintaining the quality of ecological environment in Anhui province. The quality of regional ecological environment showed a zonal distribution pattern.
Keywords:Anhui  LUCC  ecosystem service value  quality of ecosystem service
